What does an entry level traffic engineer do?

An entry level traffic engineer assists in the planning, design, and analysis of transportation systems to ensure safe and efficient movement of vehicles and pedestrians. Typical tasks include collecting and analyzing traffic data, helping design traffic signal systems, preparing reports, and using specialized software to model traffic flow.

  • Support launch pad system and flight vehicle system integrity testing to validate system health, performance and readiness for launch campaigns.
  • Lead troubleshooting efforts, resolve any issues and non-conformances that arise during operations/testing, and support anomaly investigations
  • Opportunities to perform launch console operations or launch day close out team activities
  • Write procedures for system operation, maintenance, and vehicle testing operations.
  • Develop and execute maintenance strategies that maximize system availability and minimize downtime between missions.
  • Collaborate with customers, external stakeholders, and design teams to ensure interoperability and compliance with regulatory and range safety requirements.
  • Provide technical write-ups for systems upgrade proposals or tailoring of regulations.
  • Ability to work with Fluids and Mechanical GSE team members with limited supervision to achieve project or testing objectives. Write work instructions and supervise the execution of field work in service of the launch pad fluid and pneumatic systems.

QUALIFICATIONS
Required
  • Bachelor's degree in mechanical engineering, aerospace engineering or related engineering discipline
  • 0 - 2 years of hands-on experience with fluids systems, pneumatic systems, mechanisms, hydraulic systems, tooling, flight hardware or test operations
  • Experience designing, building, troubleshooting and/or operating complex fluid or pneumatic systems in an operational or project environment.
  • Ability to create and interpret engineering documentation including drawings, P&ID schematics and test data.
  • Able to prioritize and execute tasks in a high pressure fast-paced environment
  • Ability to self-motivate and take the initiative to ensure your systems are functional and operating at peak performance
  • Ability to adapt to shifting project and/or scope change requirements
  • Ability to convey complex technical information clearly and concisely to technical and non-technical audiences
  • Comfortable working in launch site environments with field testing, lifting equipment, and hazardous materials
